Chrysanthemum plant named ‘Magnus Violet’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Magnus Violet’, characterized by its upright, outwardly spreading and rounded plant habit; moderately vigorous growth habit; freely branching habit; dense and full plant habit; large dark green-colored leaves; uniform, early and freely flowering habit; large decorative-type inflorescences with purple-colored ray florets; and excellent garden performance.

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘MAGNUS VIOLET’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, and hereinafter referred to by the name ‘Magnus Violet’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Oostnieuwkerke, Belgium. The objective of the breeding program is to create new freely flowering Chrysanthemum plants with unique and attractive ray floret coloration.

The new Chrysanthemum plant originated from a cross-pollination made by the Inventor in Oostnieuwkerke, Belgium in September, 2005 of Chrysanthemum×morifolium ‘Perano’, not patented, as the female, or seed, parent with Chrysanthemum×morifolium ‘Cassano’, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Oostnieuwkerke, Belgium in September, 2006.

Asexual reproduction of the new Chrysanthemum plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2007. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Magnus Violet’. These characteristics in combination distinguish ‘Magnus Violet’ as a new and distinct Chrysanthemum plant:

-   -   1. Upright, outwardly spreading and rounded plant habit;         moderately vigorous growth habit.     -   2. Freely branching habit; dense and full plant habit.     -   3. Large dark green-colored leaves.     -   4. Uniform, early and freely flowering habit.     -   5. Large decorative-type inflorescences with purple-colored ray         florets.     -   6. Excellent garden performance.

Plants of the new Chrysanthemum differ primarily from the female parent, ‘Perano’, in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are not as vigorous as plants         of ‘Perano’.     -   2. Plants of the new Chrysanthemum have larger leaves than         plants of ‘Perano’.     -   3. Plants of the new Chrysanthemum have larger inflorescences         than plants of ‘Perano’.     -   4. Plants of the new Chrysanthemum flower slightly later than         plants of ‘Perano’.

Plants of the new Chrysanthemum differ primarily from the male parent, ‘Cassano’, in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are not as vigorous as plants         of ‘Cassano’.     -   2. Plants of the new Chrysanthemum have larger inflorescences         than plants of ‘Cassano’.     -   3. Plants of the new Chrysanthemum flower earlier than plants of         ‘Cassano’.     -   4. Ray florets of plants of the new Chrysanthemum are darker in         color than plants of ‘Cassano’.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum×morifolium ‘Yobeth’, disclosed in U.S. Plant Pat. No. 11,818. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘Yobeth’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum were more rounded in shape         than plants of ‘Yobeth’.     -   2. Plants of the new Chrysanthemum were more flexible than and         not as brittle as plants of ‘Yobeth’.     -   3. Inflorescences of plants of the new Chrysanthemum were more         double than inflorescences of plants of ‘Yobeth’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Magnus Violet’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers during the late summer and early autumn in an outdoor nursery in Oostnieuwkerke, Belgium and under cultural practices which approximate those generally used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 25° C. to 30° C. and night temperatures ranged from 15° C. to 20° C. Plants were 20 weeks old when the photograph and detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2005 Edition, except where general terms of ordinary dictionary significance are used.
